Hello! I have a Debian 7 server with ISPconfig 3.1.11 Attached are my htf report and my mail.log. Ok I just had to do a big rebuild of my site and I'm about 90% back online with everything. So for this issue I can't send emails from my address only from either Thunderbird or Outlook. I can send messages on my phone though. I don't have squirrelmail nor roundcube set up. Thanks for all your hard work!
